【问题描述】：

我正在尝试使用 Spring Security 实现对我的 Web 应用程序的登录。 即使用户成功登录，我也会收到上述警告消息。相同的配置适用于其他应用，但不适用于这个。请帮助

我的 web.xml 文件：

显示警告： 警告 org.springframework.web.servlet.PageNotFound - 在 DispatcherServlet 中找不到带有 URI [/Webclient/home] 的 HTTP 请求的映射，名称为“dispatcher”

【问题讨论】：

错误提示 dispatcher-servlet.xml 中没有 /Webclient/home 的映射。您的控制器是否具有上述 URL 的请求映射？您可以发布具有该映射的控制器吗？

谢谢小黄人。我没有在我的控制器中映射 /home @RequestMapping(value = "/home") public String gethome() return "home"; 写了这个。现在它工作正常。

你能接受它作为答案吗？

【参考方案1】：

控制器似乎没有 /home 的映射，这就是它失败的原因。请添加并尝试一下。
